Predicted Absolute Coldest and Hottest Temperatures for 2026 by State

These forecasts pinpoint the lowest and highest single-day temperatures expected in each state, reflecting winter cold snaps and summer heatwaves that contribute to the hottest temps by state. Weโ€™ve used historical records, adjusted slightly for 2026โ€™s colder winter and warmer summer trends (about 1-2ยฐF above recent averages in many regions). All temperatures are in ยฐF and rounded for clarity. Note that local variations, like mountain peaks or coastal areas, may differ from these statewide predictions.

Fascinating Facts About 2026 Temperature Extremes

  1. Alaskaโ€™s Deep Freeze: Forecasted to hit -55ยฐF, Alaska could approach its all-time low of -80ยฐF if a polar vortex strikes. The Farmersโ€™ Almanac suggests frequent cold snaps, making it a year for heavy parkas.
  2. Californiaโ€™s Scorching Peak: A predicted 130ยฐF high puts California near its record of 134ยฐF in Death Valley. NOAAโ€™s warmer summer outlook could mean more heatwaves, especially in desert regions.
  3. Massive Temperature Swings: Montana and North Dakota could see over 160ยฐF differences between their coldest (-50ยฐF) and hottest (115ยฐF) days, thanks to their continental climate and potential La Niรฑa effects, illustrating hottest temps by state.
  4. Floridaโ€™s Milder Extremes: With a low of 5ยฐF and a high of 105ยฐF, Florida stays relatively temperate. Warming trends might push heatwaves higher, but itโ€™s still a winter haven.
  5. Snowy Northwest Chills: Washingtonโ€™s predicted -30ยฐF low aligns with the Almanacโ€™s forecast of a snowy, cold Pacific Northwest. Bundle up if youโ€™re in the Cascades!
